The 2003 Marshall R. Urist Award Paper - Genetic background of osteonecrosis: Associated with thrombophilic mutations?
(2004)Intravascular coagulation is considered a major pathogenetic mechanism for nontraumatic osteonecrosis. The aim of our study was to evaluate the association of thrombophilic factor V G1691A mutation (factor V Leiden) and ... -
Analysis of failures after vascularized fibular grafting in femoral head necrosis
(2004)Evaluation of graft-host bone interactions after failed vascularized fibular grafting of femoral head necrosis may elucidate the reasons for failure of the procedure. According to the authors' study, the vascularized fibula ... -
A capsular-based vascularized distal radius graft for proximal pole scaphoid pseudarthrosis
(2006)Purpose: To evaluate the clinical results of the application of a capsular-based dorsal distal radius vascularized bone graft in scaphoid proximal pole nonunions. Methods: Thirteen patients with symptomatic nonunion at the ... -
Early results of a novel technique using multiple small tantalum pegs for the treatment of osteonecrosis of the femoral head A CASE SERIES INVOLVING 26 HIPS
(2012)The introduction of a trabecular tantalum rod has been proposed for the management of early-stage osteonecrosis of the femoral head but serves as a single-point of support of the necrotic lesion. We describe a technique ... -
Fast sequences MR imaging at the investigation of painful skeletal sites in patients with hip osteonecrosis
(2015)Background: Multiple osteonecrotic foci can be clinically silent when located in metaphyses and becomes painful when it affects juxta-articular areas. The purpose of this study was to assess the value of fast MR imaging ... -
MR imaging findings in transient osteoporosis of the hip
(2004)Purpose: The authors sought to describe the magnetic resonance (MR) imaging findings including perfusion imaging, in association with the course of acute bone marrow oedema syndrome (aBMEs), in a group of patients with ... -
An MRI-based semiautomated volumetric quantification of hip osteonecrosis
(2001)Objective: To objectively and precisely define the spatial distribution of osteonecrosis and to investigate the influence of various factors including etiology. Design: A volumetric method is presented to describe the size ... -
Outcome after tantalum rod implantation for treatment of femoral head osteonecrosis
(2009)Background and purpose Tantalum rod implantation has recently been proposed for treatment of early stages of femoral head osteonecrosis. The purpose of our study was to report the early results of its use in pre- and ... -
Predictive role of cytokine gene polymorphisms for the development of femoral head osteonecrosis
(2012)Introduction: Osteonecrosis (ON) is a multifactorial disease that leads to hip destruction. Lately, much focus has been at femoral head preservation with nonsurgical methods. In this study we examined the polymorphisms of ... -
The role of MR imaging in scaphoid disorders
(2007)The scaphoid bone of the wrist is one of the most commonly fractured bones in the body. Due to its importance in the biomechanics and functionality of the wrist, it is important to depict and characterize the type of injury. ... -
Scaphoid nonunions treated with vascularised bone grafts: MRI assessment
(2004)Purpose: To assess the value of MR imaging (MRI) with regard to union, graft viability and proximal pole bone marrow status, after use of vascularized bone grafts for treating scaphoid nonunions. Materials and methods: ... -
Scaphoid nonunions: Management with vascularized bone grafts from the distal radius: A clinical and functional outcome study
(2007)Background: Scaphoid nonunions remain controversial with regard to optimal management, especially for those located at the proximal third. In this study, the authors aim to assess the union rate, avascular proximal pole ... -
Synovial fluid metabolites in osteonecrosis
(2007)Objectives. Osteonecrosis of the femoral head results from interruption of the vascular supply and eventual death of the cellular portion of bone. Effective methods of monitoring response to treatment are needed. Our aim ... -
Vascularized bone grafts from the palmar radius for the treatment of waist nonunions of the scaphoid
(2006)Purpose: With their intrinsic vascularity vascularized bone grafts provide an alternative solution to the challenging problem of scaphoid nonunions. The union rate (after imaging evaluation including magnetic resonance ... -
Vascularized periosteal flaps of distal forearm and hand
(2005)Background: Vascularized periosteal flaps (VPFs) are flexible osteogenic flaps, suitable for the reconstruction of small skeletal defects. Pedicled VPFs, harvested near the recipient site, minimize donor-site morbidity and ...
